Consider the following statements : Statement-I : Many chewing gums found in the market are considered a source of environmental pollution. Statement-II : Many chewing gums contain plastic as gum base. Which one of the following is correct in respect of the above statements ?
ABoth Statement-I and Statement-II are correct and Statement-II explains Statement-I
BBoth Statement-I and Statement-II are correct, but Statement-II does not explain Statement-I
CStatement-I is correct, but Statement-II is incorrect
DStatement-I is incorrect, but Statement-II is correct
Answer & Solution
Correct answer: A. Both Statement-I and Statement-II are correct and Statement-II explains Statement-I
Answer: A. Both statements are correct and Statement-II explains Statement-I.
Statement-I: Chewing gums are widely recognised as a source of environmental pollution. They are notoriously hard to clean off streets and remain non-biodegradable in landfills and waterways. CORRECT.
Statement-II: The 'gum base' in most commercial chewing gums is made of synthetic polymers — polyisobutylene, polyvinyl acetate or styrene-butadiene rubber. These are essentially plastics, which is what makes the gum non-biodegradable and a pollution source. CORRECT and DIRECTLY EXPLAINS Statement-I.
The plastic gum base is the actual mechanism causing the pollution, so Statement-II provides the causal explanation for Statement-I.
